The German Constitutional Court has been developping a new theory with regard to the constitutional protection of the property right since its decisions on the 15th July, 1981. As its decisions differ basically from the former civil court decisions, German lawyers often speak of a paradigm change in the property right theory. However, the German Constitutional Court had given several decisions to the same effect already in 1960's and 1970's. The first one was so-called "Feldmuehle"-decision in 1962, the second one was in 1971. Professor Lerke Osterloh, who later became judge in the Constitutional Court, argued according to these court decisions that the compensation can be required not only in taking cases, but also in statutory limitations of the property rights.
